I'm developing a CompositeControl which contains 3 child controls.
My problem is: when the page is posted back, the LoadViewState of my control is called before that of child controls, i.e. in the LoadViewState method, child controls are not ready. I want to find a place where the child controls' states are ready for use so that I can use them to restore some data field of the parent control. I try the LoadPostData method, but it is not called when the page is posted back like the document says.
So my questions are:
1. In what event the states of child controls are ready for use?
2. Why is the LoadPostData method not called?
Thank you for reading.
